How To Make Dual Bootable USB Drive With Two Windows 10 Versions [Tutorial]

Creating a bootable USB drive has become a common task for a tech-savvy user. With a bit of practice, it becomes an easy task like snapping your finger. Today I’m going to share with you a more advanced version of what you were doing already. In this tutorial, I will give a step by step guide on how you can put two Windows 10 versions on one USB stick to make it dual bootable.

Why will you be needing a bootable USB disk? Well, in case you are Microsoft beta user and switch frequently between Stable and Insider build of Windows 10 then it’s good to have both stable and insider build on a flash drive so you won’t have to install both versions of Windows 10 every time you like to change Windows. In another case, your Windows can get corrupted in that case too a bootable flash drive will come handy. Here I will show you how to do just that. Let’s get started, shall we?

How To Make Dual Bootable USB Drive With Two Windows 10 Versions [Tutorial]

Choose a flash drive (preferably blank, and at least 16 GB in capacity).

After logging in, on Insider page check for System Requirements before downloading any Preview Build.

Scroll down to “Select Edition” and choose from the latest builds available. As of now, the insider build (Windows 10 Client Insider Preview – Build 17713 English) is older than my already installed Consumer build (Windows 10, version 1803), whenever they are available you can go ahead and download it from this page.

Once the files are downloaded, make copies and then drag-and-drop the copies to the _ISO\WINDOWS\WIN10 folder.

Once the files are copied and you’re sure they’re in the appropriate location, go to the root directory of the flash drive and run the “MAKE_THIS_DRIVE_CONTIGUOUS.cmd” file, to make the drive bootable.

This tutorial is not Windows-only; it can be used with Linux and DOS ISOs as well, so this could be used to create a Swiss Army knife disc, that boots from Windows 10/8.x/7/Vista/XP, Ubuntu/Fedora/Linux Mint/openSUSE/Mandriva/any Linux distro, as well as tool-based/recovery distributions, so your flash drive could become the ultimate Windows repair disk with this tutorial.
